Description

After initiating the replication in both the Masters, for the first few minutes replication was successful. But, after sometime, the connection closes. I see that COUCHDB-2834 has a fix but it is not for version CouchDB 1.6.0. Here is the Replication detail

Replication `"80b3311cc764e56900e704938f84727b+continuous"` is using:
4 worker processes
a worker batch size of 500
20 HTTP connections
a connection timeout of 30000 milliseconds
10 retries per request
socket options are: [

{keepalive,true}

,

{nodelay,false}

]
source start sequence 21

Here is the error log after the connection is closed

  • {http_request_failed,"PUT",
